Cannabis Seeds are a valuable asset – both for passionate growers and dedicated collectors. To ensure they retain their full germination ability for months or even years, proper storage is essential. In this article, you will learn how to optimally store Cannabis Seeds, what to watch out for, and which mistakes to avoid.
Why is proper storage of Cannabis Seeds so important?
Cannabis Seeds are living organisms in a dormant state. Under ideal conditions, they can survive for years – but only if protected from moisture, light, heat, and oxygen. Poor storage can lead to mold growth, drying out, or premature germination. This means in the worst case: unusable Seeds and a frustrating start to the next grow season.
The 4 enemies of germination ability
Before we get to the best storage methods, let's look at the biggest dangers for Cannabis Seeds:
- Moisture: A moisture level above 60% can cause mold or premature germination.
- Heat: High temperatures accelerate the aging process and reduce germination ability.
- Light: UV radiation can damage the cell structure and shorten lifespan.
- Oxygen: Oxidation causes the Seeds to "age," lowering their germination rate.
Proper storage of Cannabis Seeds: The best methods
1. Store cool, dark, and dry
The ideal environment for Cannabis Seeds is:
- Temperature: 4–8 °C (similar to a refrigerator)
- Humidity: 30-40 %
- Light: completely dark
2. Use airtight containers
The best options are:
- Vacuum-sealed bags
- Small screw jars with silica gel (a granular, porous drying agent used to bind moisture from the air)
- Special Seed boxes or opaque cans
3. Store in the refrigerator
A constant cool space like the vegetable compartment in the refrigerator is ideal. Important: Only open containers at room temperature to avoid condensation.
Long-term storage: How Cannabis Seeds remain viable for years
- Use vacuum bags or jars with silica gel.
- If possible: place them in a separate refrigerator that is rarely opened.
- Label the Seeds with strain and date to keep track.
Common storage mistakes
- Plastic bags without protection: They allow oxygen through and offer no light protection.
- Daylight: UV rays are germination ability's number one enemy.
- Freezer compartment: Freezing can destroy the cell structure, especially with temperature fluctuations.
Storage determines quality
Proper storage of Cannabis Seeds is the key to healthy plants and successful grows. With some planning and the right materials, you can store your Seeds for many years without quality loss. That is why House Of Seeds always stores all Cannabis Seeds cool and dry in specially designated refrigerators – to ensure maximum freshness and germination ability. Not sure which strain suits you?
